The 17th century however, proved a time of great turbulence. Giggleswick parish favoured Oliver Cromwell’s side during the Commonwealth period and seems to have been greatly influenced by strands of Puritan “low” church theology and some practices which have left their mark almost to the present day. From 1643-7, Oliver Cromwell and his Commonwealth government set about destroying the Church of England as it had been nurtured by the English Reformers and the Elizabethan Settlement. The Book of Common Prayer was proscribed, just when Anglicans were beginning to value it. Ecclesiastical government and ministry by bishops, priests and deacons were abandoned. Universities were purged and many clergy evicted from their parishes. Church wardens were directed to remove all monuments of idolatry and superstition, such as stained-glass, statues, carvings on walls etc, in fact, anything that had escaped the first purging of a century before. Many items were thrown or buried in churchyards because church officers could not bring themselves to throw what had been considered holy, on to the common rubbish heap. Churches were to be utterly plain in furnishings with the emphasis on the pulpit, the English Bible, preaching and the written and spoken Word. Biblical scenes and paintings of saints on walls were whitewashed. In their place appeared painted texts, the Ten commandments and the Apostles Creed as on the east wall in Giggleswick Church, although these are late 19th century replacements. The practice of the Sacrament of Holy Communion became only occasional and there were certainly no lit candles on what could be clearly seen was an unadorned, movable table, and no longer a fixed and covered altar. Moreover, the feasting, dancing and celebratory parts of church festivals including Christmas, were banned throughout the whole Commonwealth period.
